Can't beat random orcs in the woods in Black Feather
So I made a mage team, and i've been pretty much coasting through the game up until this point, including through Black Feather. All that was fine until I came upon these damn Orcs in the woods.
My team: Elpis(+5), Helena (+5), Diana, Dalvi, Eclipse, all at max level. This team has beaten everything so far.
Round 1, 3 of them die, then they immediately kill everyone excel Eclipse, who is at half health. I have no SP, she hits one enemy, and then dies.
Tried my physical team, Liberta, eleaneer, Lathel, Nebris, Sacred Justia, and exactly the same thing happens excel Liberta is the only one left alive.
I am sure there is some kind of gimmick to this fight, but I can't figure it out, and I can't find any guides that aren't 2+ years old and out of date.
What do I need to get past this stupid combat?
